How much of our planet is not covered by the sea?

Q. Read the following passage carefully and answer the questions that follow :

Three-fourth of the Earth is covered by the sea which both separates and unites the various races of mankind. The sea is the great highway along which man may travel at his will, the great road that has no walls or hedges hemming it in. Nobody needs to keep it in good repair with the helps of pickaxes and barrels of tar and steamrollers. The sea appeals to man’s love of the perilous and the unknown, to his love of conquest, his love of knowledge and his love of gold. Its blue waters call to him and bid him fare forth in quest of fresh fields. Beyond their horizon he has found danger and death, glory and gain.
